Overview
Thank you for purchasing the R100 Wireless Gateway. The R100
complies with IEEE 802.11g and 802.11b standards. The 802.11g is
an extension to 802.11b (used in the majority of wireless LANs today)
that broadens 802.11b’s data rates to 54 Mbps within the 2.4 GHz
band using OFDM (orthogonal frequency division multiplexing)
technology. The 802.11g allows backward compatibility with 802.11b
devices but only at 11 Mbps or lower, depending on the range and
presence of obstructions. Wireless LANs are complementary
extensions to existing wired LANs, offering complete mobility while
maintaining continuous network connectivity to both corporate and
home Intranets. They add a new level of convenience for LAN users,
as PC’s stay connected to the network anywhere throughout a building
without being bound by wires. This is accomplished through the use
of the Access Point functionality of the Wireless Gateway. The builtin Internet gateway capability allows your family to share a broadband
Modem and one ISP account simultaneously from different rooms
without wires!

Configuring the R100 Wireless Gateway
The gateway can be configured to meet various usage scenarios. Some
of the factory default settings may suit your usage, however, others
may need changing. Prior to using the gateway, you must check the
basic settings to guarantee it will work in your environment. Configuring
the gateway is done through a web browser. You need a Notebook PC
or desktop PC connected to the gateway (either directly or through a
network hub) and be running a web browser as a configuration terminal.
The connection can be wired or wireless. For the wireless connection,
you need an IEEE 802.11g/b compatible device (e.g. a WLAN Card,
installed in your Notebook PC). You should also disable WEP and set
the SSID to “default” for your wireless LAN device. If you want to
configure the gateway or want to access the Internet through the
gateway, the TCP/IP settings must be correct. Normally, the TCP/IP
settings should be on the IP subnet of the R100 Wireless Gateway.
3. Utilities
Note: Before rebooting your computer, the R100 Wireless Gateway
should be switched ON and in the ready state.
Setting an IP address for the Wired or Wireless Connection
Getting the IP Automatically
The R100 Wireless Gateway

SSID
The SSID is an identification string of up to 32 ASCII characters that
differentiate one R100 Wireless Gateway Access Point (AP) from
another. The SSID is also referred to as the “ESSID” or “Extended
Service Set ID.” You can use the default SSID and radio channel unless
more than one R100 or Access Point is deployed in the same area. In
that case, you should use a different SSID and radio channel for each
R100 or Access Point. All R100 Wireless Gateways and Diamond
Digital 802.11g/802.11b WLAN client adaptors must have the same
SSID to allow a wireless mobile client to roam between the R100s. By
default, the SSID is set to “default”.

Chapter 3 - Software Configuration
Channel
The 802.11g and 802.11b specifications supports up to 14 overlapping
channels for radio communication. To minimize interference, configure
each 802.11g AP to be non-overlapping; select Auto from the Channel
drop-down list to enable the system to select a clear channel during
boot up as your operating channel.
Ensure that any R100 Wireless Gateways sharing the same channel
(or channels which are close in number) are as far away from each
other as possible, based on the results of your site survey of the
facility. There is a site survey utility on the R100 Driver CD.
Wireless Mode
This field allows you to specify the transmission rate. Selecting Auto
(recommended) allows 802.11g and 802.11b clients to connect to the
R100 Wireless Gateway. Selecting 54G Only maximizes performance,
but prevents 802.11b clients from connecting to the gateway. If 54g
Protection is checked, G-Mode protection of 11g traffic is enabled
automatically in the presence of 11b traffic. Select 802.11b only when
backward compatibility is needed for some older wireless LAN cards
with a maximum bit rate of 2Mbps.
3. Utilities
Authentication Method
This field enables you to set different authentication methods which
determine different encryption schemes. The relationship between
Authentication Method, Encryption, Passphrase and WEP Keys is
listed in the following table. If you are not using a RADIUS server in a
home environment and all your clients support WPA, using WPA-
PSK is recommended for better security. If WPA or Radius with 802.1x,
is selected, additional settings for the RADIUS server in the Wireless
– Radius field are required.

which works simultaneously on multiple network layers.
64/128-bit versus 40/104-bit
The following section explains low-level (64-bit) and high-level (128bit) WEP Encryption schemes:
64-bit WEP Encryption
30 R100 Wireless Gateway
Chapter 3 - Software Configuration
64-bit WEP and 40-bit WEP are the same encryption method and
can interoperate in a wireless network. This level of WEP encryption
uses a 40-bit (10 Hex character) encryption scheme as a secret key,
which is set by the user, and a 24-bit “Initialisation Vector” scheme,
which is not under user control.
Together these two schemes make a 64-bit (40 + 24) encryption
scheme. Some vendors refer to this level of WEP as 40-bit and others
refer to this as 64-bit. Diamond Digital WLAN products use the term
64-bit when referring to this lower level of encryption.
128-bit WEP Encryption
104-bit WEP and 128-bit WEP are the same encryption method and
can interoperate on a wireless network. This level of WEP encryption
uses a 104-bit (26 Hex character) encryption scheme as a secret key
which is set by the user, and a 24-bit “Initialisation Vector”, which is
not under user control.
Together these two schemes make a 128-bit (104 + 24) encryption
scheme. Some vendors refer to this level of WEP as 104-bit and others
refer to this as 128-bit. Diamond Digital WLAN products use the term
128-bit when referring to this higher level of encryption.
Passphrase
Selecting TKIP or AES in the Encryption field is used as a password
to begin the encryption process. Note: 8 to 63 characters are required.
Selecting WEP-64bits or WEP-128bits in the Encryption field generates
four WEP keys automatically. A combination of up to 64 letters,
numbers, or symbols is required. Alternatively, leave this field blank
and type in four WEP keys manually.
• WEP-64bit key: 10 hexadecimal digits (0~9, a~f, and A~F)
• WEP-128bit key: 26 hexadecimal digits (0~9, a~f, and A~F)
Note: The Diamond Digital WLAN family of products uses the same
algorithm to generate WEP keys, eliminating the need for users to
remember passwords and to maintain compatibility between
products. However, using this method to generate WEP keys is not
as secure as manual assignment.

R100 Wireless Gateway 31
WEP Key
You can set a maximum of four WEP keys. A WEP key is either 10 or
26 hexadecimal digits (0~9, a~f, and A~F) based on whether you
select 64bits or 128bits in the WEP drop-down menu. The R100
Wireless Gateway and ALL of its wireless clients MUST have at least
the same default key.
Key Index
The Key Index field lets you specify which of the four encryption keys
you use to transmit data on your wireless LAN. As long as the R100
Wireless Gateway or wireless mobile client with which you are
communicating has the same key in the same position, you can use
any of the keys as the key index. If the R100 and ALL of its wireless
clients use the same four WEP keys, select key rotation to maximize
security. Otherwise, choose one key in common as the key index.

.
Wireless Gateway
In Wireless Gateway mode, the WAN
port is assumed to attach to the Internet
via a Cable or DSL modem. This allows
several wireless clients and PCs
attached to the LAN ports to share the
Internet connection to the ISP.
Technically, gateway mode means, NAT
is enabled and WAN connection is
allowed by using PPPoE, DHCP client,
or static IP. In addition, some features,
which are useful for home users, such
as UPnP and DDNS are supported.
Router
In Router mode, we assume you’re using the Ethernet port to connect to a LAN in
your company. This way, you can set up a routing protocol to meet your requirements
in the office.
Technically, router mode means NAT is disabled, static and dynamic routing protocol
are allowed to be set, and WAN connection is allowed only by using a static IP.
Access Point
In Access Point mode, the gateway acts as a bridge between the PCs attached
to all Ethernet ports (LAN) and the clients on the wireless LAN (WLAN). Both
the LAN and WLAN will be on the same IP subnet, sharing the same address
range. The internal NAT is disabled in this mode
Technically, access point mode means NAT is disabled, and one WAN port
and four LAN ports are bridged together.
By default, the R100 Wireless Gateway operates in Access Point mode.

4. Wireless Performance4. Wireless Performance
This section provides the user with ideas for how to improve the
performance of a R100 Wireless Gateway.
Site Topography
For optimal performance, position wireless mobile clients and the R100
Wireless Gateways away from transformers, heavy-duty motors,
fluorescent lights, microwave ovens, refrigerators, and other industrial
equipment. Signal loss can occur when metal, concrete, walls or floors
block transmission. Situate the R100s in open areas or add additional
R100 gateways as needed to improve coverage.
Microwave ovens operate in the same frequency band as the R100.
Therefore, if you use a microwave within range of the gateway you
may notice network performance degradation. However, both your
microwave and the R100 Wireless Gateway will continue to function.
Site Surveys
A site survey (utility provided with the WLAN PC card and CF card)
analyses the installation environment and provides users with
recommendations for equipment and its placement. The optimum
placement differs for each model.
4. Performance
R100 Wireless Gateway 83
Chapter 4 - Wireless Performance
Range
Every environment is unique with different obstacles, barriers,
materials, etc. and, therefore, it is difficult to determine the exact
range that will be achieved without testing. However, some guidelines
have been developed to estimate the range that users will see when
the product is installed in their facility, but there are no hard and fast
specifications.
Radio signals may reflect off some obstacles or be absorbed by others
depending on their construction. For example, with two 802.11b radios,
you may achieve up to 1000 feet in open space outdoors where two
devices have a line of sight, meaning they see each other with no
obstacles. However, the same two units may only achieve up to 300
feet of range when used indoors.
The IEEE 802.11b specification supports four data rates: 11 Mbps,
5.5 Mbps, 2 Mbps, and 1 Mbps. Operation at 1 Mbps provides greater
range than operation at 11 Mbps. The R100 Wireless Gateway will
automatically adjust the data rate to maintain a usable radio connection.
Therefore, a client that is close to the gateway may operate at 11
4. Performance
Mbps while a client that is on the fringe of coverage may operate at 1
Mbps. As mentioned earlier, you can configure the data rates that the
R100 Wireless Gateway will use. Note that if you limit the range of
data rates available to the gateway, you may reduce the effective
wireless range of the Diamond Digital Wireless products.

Troubleshooting
The R100 Wireless Gateway is designed to be very easy to install and
operate. However, if you experience difficulties, use the information in
this chapter to help diagnose and solve problems. If you cannot resolve
a problem, contact Technical Support, as listed at the back of this
manual.
Common Problems and Solutions
Problem
Gateway does not power up:
Solution
• Check for a faulty power supply by measuring the output voltage of
the adaptor with an electrical test meter.
• Check failed AC supply (power outlet)
Problem
Cannot communicate with the Wireless Gateway through a wired
network connection.
Solution
• Verify network configuration by ensuring that there are no duplicate IP
addresses. Power down the device in question and ping the assigned
IP address of the device. Ensure no other device responds to that
address.
• Check that the cables used have proper pin outs and connectors or
use another network cable.
Troubleshooting
R100 Wireless Gateway 85
Appendix -Troubleshooting
Problem
The R100 Wireless Gateway Web Manager still cannot find or connect
to the gateway after verifying the IP address and network cable, changes
cannot be made, or password is lost.
Solution
In the case of the gateway being inaccessible, you can restore the
R100’s factory default settings. Use a straightened paper clip to press
the button located in the hole labeled Reset on the back of the gateway
and keep it depressed over 5 seconds. The LEDs will flash when reset
is successful.
Reset to Defaults
The following are factory default values. These values will be present when
you first receive your R100 Wireless Gateway, if you push the reset button
on the back of the gateway for over 5 seconds, or if you click the Restore

Solution
Follow these steps:
1. Try to bring the devices closer together; the PC Card may be out of
range of the R100.
2. Confirm that the R100 and PC Card have the same SSID.
3. Confirm that the R100 and PC Card have the same Encryption settings,
if enabled.
4. Confirm that the R100’s Air and Link LEDs are solid green.
5. Confirm that the authorization table includes or excludes the MAC
address of the WLAN PC card if Wireless Access Control is enabled.
Problem
The throughput seems slow.
Solution
To achieve maximum throughput, verify that your antennas are wellplaced, not behind metal, and do not have too many obstacles between
them. If you move the client closer to the R100 and throughput
increases, you may want to consider adding a second R100 Gateway
and implementing roaming.
• Check antenna, connectors and cabling.
• Verify network traffic does not exceed 37% of bandwidth.
• Check to see that the wired network does not exceed 10 broadcast
messages per second.
• Verify wired network topology and configuration.

Wireless Gateway with a subnet different from your computer within
the same gateway. You must change your computer to the same
subnet as the R100s. The factory default subnet of the R100 Wireless
Gateway is 192.168.1.1.
In Windows NT/2000/XP, you must log in with Administrator privileges so that all functions of the R100 Wireless Gateway Manager
can function correctly. If you do not log in as a member of the Administrator group, you cannot change IP settings but can still run the
Discovery utility if the original IP setting is correct.

Appendix - Glossary
Glossary
Access Point - An access point is a device that allows wireless clients
to connect to other wireless clients and it acts as a bridge between
wireless clients and a wired Ethernet network.
Broadband - A type of data transmission in which a single medium
(such as cable) carries several channels of data at once.
Channel - Wireless access points allow you to choose different radio
channels in the wireless spectrum. A wireless LAN device operates
within the 2.4 GHz spectrum and a channel is within a FCC specified
range, similar to any radio channel.
Client - A client is the desktop or mobile PC that is connected to your
network.
Device name - Also known as DHCP client ID or network name.
Sometimes provided by an ISP when using DHCP to assign addresses.
DHCP (Dynamic Host Configuration Protocol) - This protocol allows
a computer (or many computers on your network) to be automatically
assigned a single IP address from a DHCP server.
DNS Server Address (Domain Name System) - DNS allows Internet
host computers to have a domain name and one or more IP addresses.
A DNS server keeps a database of host computers and their respective
domain names and IP addresses, so that when a user enters a domain
name into the Internet browser, the user is sent to the proper IP address.
The DNS server address used by the computers on your home network
is the location of the DNS server your ISP has assigned.
DSL Modem (Digital Subscriber Line) - A DSL modem uses your
existing phone lines to transmit data at high speeds.
Encryption - This provides wireless data transmissions with a level of
security.
ESSID (Extended Service Set Identifier) - You must have the same
ESSID entered into the gateway and each of its wireless clients. The
ESSID is a unique identifier for your wireless network.
Ethernet - Ethernet networks are connected by cables and hubs,
and move data around. This is a standard for computer networks.

Frame-bursting - Refers to burst mode. Burst mode optionally allows
a station to transmit a series of frames without relinquishing control of
the transmission medium.
Firewall - A firewall determines which information passes in and out
of a network. NAT can create a natural firewall by hiding a local
network’s IP addresses from the Internet. A Firewall prevents anyone
outside of your network from accessing your computer and possibly
damaging or viewing your files.
Gateway - A network point that manages all the data traffic of your
network, as well as to the Internet and connects one network to another.
Handshaking - handshaking refers to the signals that are transmitted
between communications networks that establish a valid connection
between two stations.
IEEE - The Institute of Electrical and Electronics Engineers. The IEEE
sets standards for networking, including Ethernet LANs. IEEE
standards ensure interoperability between systems of the same type.
IP Address (Internet Protocol) - An IP address consists of a series
of four numbers separated by periods, that identifies a unique Internet
computer host, allowing messages intended for that computer to be
delivered to the correct destination.
ISP (Internet Service Provider) - An ISP is a business that allows
individuals or businesses to connect to the Internet. Users log on to
the Internet using an account with an ISP or Internet Service Provider.
ISPs can serve IP addresses dynamically, or assign static (fixed) IP
addresses to individual computers.
ISP Gateway Address - The ISP Gateway Address is an IP address
for the Internet router. This address is only required when using a
cable or DSL modem.
LAN (Local Area Network) - A LAN is a group of computers and
devices connected together in a relatively small area (such as a house
or an office). Your home network is considered a LAN.
MAC Address (Media Access Control) - A MAC address is the
Appendix
hardware address of a network device.
90 R100 Wireless Gateway
Appendix - Glossary
NAT (Network Address Translation) - NAT masks a local network’s
group of IP addresses from the external network, allowing a local
network of computers to share a single ISP account. This process
allows all of the computers on your home network to use one IP
address. This will enable access to the Internet from any computer on
your home network without having to purchase more IP addresses
from your ISP.
PC Card - This is an Ethernet card that connects to the PCMCIA slot
on your Notebook PC. This enables the computer to communicate
with wireless access points.
PPP (Point-to-Point Protocol) - PPP is a protocol for communication
between computers using a serial interface, typically a personal
computer connected by phone line to a server.
PPPoE (Point-to-Point Protocol over Ethernet) - Point-to-Point
Protocol is a method of secure data transmission. PPP using Ethernet
to connect to an ISP.
Subnet Mask - A subnet mask is a set of four numbers configured
like an IP address. It is used to create IP address numbers used only
within a particular network.
TCP/IP (Transmission Control Protocol/Internet Protocol) - This
is the standard protocol for data transmission over the Internet.
Protocols used to connect hosts on the Internet.
WAN (Wide Area Network) - A system of LANs, connected together.
A network that connects computers located in separate areas, (i.e.,
different buildings, cities, countries). The Internet is a wide area network.
WECA (Wireless Ethernet Compatibility Alliance) - An industry
group that certifies cross-vender interoperability and compatibility of
IEEE 802.11b wireless networking products and to promote that
standard for enterprise, small business, and home environments.
WLAN (Wireless Local Area Network) - This is a group of computers
and other devices connected wirelessly in a small area. A wireless
network is referred to as LAN or WLAN.

Appendix
Appendix - GNU General Public License
Preamble
The licenses for most software are designed to take away your freedom
to share and change it. By contrast, he GNU General Public License is
intended to guarantee your freedom to share and change free software—
to make sure the software is free for all its users. This General Public
License applies to most of the Free Software Foundation’s software and
to any ther program whose authors commit to using it. (Some other Free
Software Foundation software is covered by the GNU Library General
Public License instead.) You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price.
Our General Public Licenses are designed to make sure that you have
the freedom to distribute copies of free software (and charge for this
service if you wish), that you receive source code or can get it if you want
it, that you can chnge the software or use pieces of it in new free programs;
and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to
deny you these rights or to ask you to surrender the rights. These restritions
translate to certain responsibilities for you if you distribute copies of the
software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or
for a fee, you must give the recipients all the rights that ou have. You must
make sure that they, too, receive or can get the source code. And you must
show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2)
offer you this license which gies you legal permission to copy, distribute
and/or modify the software.
Also, for each author’s protection and ours, we want to make certain that
everyone understands that there is no warranty for this free software. If the
software is modified by soeone else and passed on, we want its recipients
to know that what they have is not the original, so that any problems
introduced by others will not reflect on the original authors’ reputations.
Finally, any free program is threatened constantly by sftware patents. We
wish to avoid the danger that redistributors of a free program will individually
obtain patent licenses, in effect making the program proprietary. To prevent
this, we have made it clear that any patent must be licensed for everyone’s
ree use or not licensed at all.
The precise terms and conditions for copying, distribution and modification
Appendix
follow.
94 R100 Wireless Gateway
Appendix - GNU General Public License
Terms & conditions for copying, distribution, & modification
0. This License applies to any proram or other work which contains a
notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The “Program”, below,
refers to any such program or work, and a “work based on the Program”
means eitherthe Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it, either
verbatim or with modifications and/or translated into another language.
(Hereinafter, translation is included without limitaton in the term
“modification”.) Each licensee is addressed as “you”.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of running
the Program is not restricted, and the otput from the Program is covered
only if its contents constitute a work based on the Program
(independent of having been made by running the Program). Whether
that is true depends on what the Program does.
1. You may copy and distribute verbatim copis of the Program’s source
code as you receive it, in any medium, provided that you conspicuously
and appropriately publish on each copy an appropriate copyright notice
and disclaimer of warranty; keep intact all the notices that refer to this
License and o the absence of any warranty; and give any other
recipients of the Program a copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchang for a fee.
2. You may modify your copy or copies of the Program or any portion of
it, thus forming a work based on the Program, and copy and distribute
such modifications or work under the terms of Section 1 above, provided
that you also meet all ofthese conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or s derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
R100 Wireless Gateway 95
Appendix
Appendix - GNU General Public License
c) If the modified program normally reads commands interactively
when run, you must cause it, when started unning for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute th program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but does
not normally print such an announcement, your work based on
the Program is not required to print an announement.)
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Program, and can be
reasonably considered independent and separate works in themselves,
then this License, and its terms, d not apply to those sections when
you distribute them as separate works. But when you distribute the
same sections as part of a whole which is a work based on the Program,
the distribution of the whole must be on the terms of this License,
whose permissons for other licensees extend to the entire whole, and
thus to each and every part regardless of who wrote it.
3. You may copy and distribute the Program (or a work based on it,
Appendix
Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to xercise
the right to control the distribution of derivative or collective works
based on the Program.
In addition, mere aggregation of another work not based on the
Program with the Program (or with a work based on the Program) on
a volume of a storageor distribution medium does not bring the other
work under the scope of this License.
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provded that you also do one of the following:
a) Accompany it with the complete corresponding machine-
readable source code, which must be distributed under the terms
of Sections 1 and 2 above on a medium customarily used for
software interchange; or,
96 R100 Wireless Gateway
Appendix - GNU General Public License
b) Accompany it with a written offer, valid for at least three years,
to give any third party, for a charge no more than your cost of
physically performing source distribution, a complete machinereadable copy of the corresponding source code, to bedistributed
under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowe only for noncommercial distribution and only if you
received the program in object code or executable form with
such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modificationsto it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to control
compilation and installation of the executable. However, as a spcial
exception, the source code distributed need not include anything that
is normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that omponent itself accompanies
the executable.
If distribution of executable or object code is made by offering access
to copy from a designated place, then offering equivalent access to
copy the source code from the same place counts as distribution of
te source code, even though third parties are not compelled to copy
the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program except
as expressly provided under this License. Any attempt otherwise to
cop, modify, sublicense or distribute the Program is void, and will
automatically terminate your rights under this License. However, parties
who have received copies, or rights, from you under this License will
not have their licenses terminated so long as sch parties remain in full
compliance.
Appendix
R100 Wireless Gateway 97
Appendix - GNU General Public License
5. You are not required to accept this License, since you have not signed
it. However, nothing else grants you permission to modify or distribute
the Program or its derivative works. These actions are prohibite by
law if you do not accept this License. Therefore, by modifying or
distributing the Program (or any work based on the Program), you
indicate your acceptance of this License to do so, and all its terms
and conditions for copying, distributing or modifing the Program or
works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the original
licensor to copy, distribute or modify the Program subject to these
trms and conditions. You may not impose any further restrictions on
the recipients’ exercise of the rights granted herein. You are not
responsible for enforcing compliance by third parties to this License.
7. If, as a consequence of a court judgmentor allegation of patent
Appendix
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the coditions of this License. If you cannot distribute
so as to satisfy simultaneously your obligations under this License
and any other pertinent obligations, then as a consequence you may
not distribute the Program at all. For example, if a patent license ould
not permit royalty-free redistribution of the Program by all those who
receive copies directly or indirectly through you, then the only way
you could satisfy both it and this License would be to refrain entirely
from distribution of the Program.
I any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this sectin to induce you to infringe any patents
or other property right claims or to contest validity of any such claims;
this section has the sole purpose of protecting the integrity of the free
software distribution system, which is implemented by public licens
practices. Many people have made generous contributions to the
wide range of software distributed through that system in reliance on
consistent application of that system; it is up to the author/donor to
decide if he or she is willing to distribute softare through any other
system and a licensee cannot impose that choice.
98 R100 Wireless Gateway
Appendix - GNU General Public License
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restrictd in certain
countries either by patents or by copyrighted interfaces, the original
copyright holder who places the Program under this License may add
an explicit geographical distribution limitation excluding those
countries, so that distribution is permtted only in or among countries
not thus excluded. In such case, this License incorporates the limitation
as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public Licens from time to time. Such new versions
will be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of his License which applies to it and “any
later version”, you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number
f this License, you may choose any version ever published by the
Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs
whose distribution conditions are different, write to the author to ask
for permision. For software which is copyrighted by the Free Software
Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two
goals of preserving the free status of all derivatives of our fre software
and of promoting the sharing and reuse of software generally.

NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE,
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT
PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATEDIN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER
PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
TH ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF
THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
SERVICING, REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR
AGREED TO IN WRTING WILL ANY COPYRIGHT HOLDER, OR
ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL
OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
INABILITY TO SE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE
OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS
BEEN ADVISED OFTHE POSSIBILITY OF SUCH DAMAGES.
